I going to try this again. I am a long time KTM rider. I need a second bike for numerous reasons. I have always liked the Yamaha thumpers, so I am going to buy one (I think). I have a line on a 2002 WR426 that I can get for $2500. It is in incredible condition, with extras, like O-ring, Ironman sprockets, Scott's ready, exc. It has a popping or hesitating during acceleration. It is YZ timed, has a new black box, and the carb has been gone through numerous times. It had this problem even before the YZ timing. Here are my series of questions: - did the '02-WR have any reported CAM problems (mis-ground) - Any common electrical problems - Any Valve train issues - A few KTMs had the bottom part of the slide installed backwards that created issues - any Yamahas have this problem. I do not want to become a frustrated Yamaha owner after years of owning KTM's, but I have always liked them and HAVE to give it a try. HELP!!
